It wasn't pretty. But the Miami Dolphins pulled out a 17-10 road win over the Washington Redskins.

Now that Miami put a regular-season game on film, here are some early reasons for Dolphins fans to be optimistic.

Jarvis Landry: Miami's second-year receiver was one of the most consistent players in training camp. Therefore, there is no surprise he showed up when the Dolphins needed him most in the second half. Miami struggled offensively, but Landry had some timely catches late in the third quarter that led to a game-tying field goal. His 69-yard punt return in the fourth quarter broke open the game for Miami. Landry continues to have a knack for the big moment.

Cornerbacks: The Dolphins received both big plays and steady plays from their cornerbacks Sunday. Pro Bowler Brent Grimes sparked the Dolphins with a first-half interception off quarterback Kirk Cousins that led to Miami's only field goal. There were questions about whether Miami had enough depth behind Grimes. But fellow starter Brice McCain also made an athletic interception in the fourth quarter to help close out the game, and Jamar Taylor had a solid game in the nickel spot minus one penalty.

Jordan Cameron: Miami's starting tight end had four catches for 74 yards in his Dolphins debut. He showed flashes of the 2013 Pro Bowl form, having the athleticism to get behind Washington's linebackers for big plays. Jordan didn't get much activity in the preseason with just one catch for 6 yards. But he erased many of those questions in Week 1. Jordan is expected to play a big role, especially with backup tight end Dion Sims (concussion) likely to miss time.
